Abstract

Floods are the number one natural disaster in the Nation, based on loss of life and property. In Indiana, several major floods have occurred during this century. Flooding can occur at any time in any geographic area in Indiana. The degree of flooding can vary from a minor inconvenience to major flooding that results in loss of life and extensive damage. In this study, the existing streamflow-gaging networks in Indiana are evaluated on the basis of meeting flood-data needs of various governmental agencies. The study area (Indiana and adjacent areas in Illinois, Michigan, and Ohio) was divided into 12 basins and 1 urban area. Each basin and the Indianapolis area were analyzed on the basis of hydrologic characteristics, flood potential, and availability and benefits of real-time data. A set of guidelines for evaluating an existing streamflow- gaging station without telemetry was developed so quantitative comparisons could be made between stations. The guidelines include station-site characteristics of drainage area, peak discharge, population of the nearby area, and needs of government agencies for planning and flood-warning management. From the analyses, determinations were made concerning modifications or additions to the networks to improve flood-data collection and transmission. These determinations were discussed at interagency meetings to ensure agreement. The study results indicate that installation of streamflow-gaging stations at 15 new sites would improve collection of flood data. Instrumenting the 15 new sites plus 26 existing streamflow-gaging stations with telemetry, preferably data-collection platforms with satellite transmitters, would improve transmission of data to users of the information.
